. "0 all whom, it mayconcern:

Be it known that I, ALBERT A.WOOD, a citizen of the UnitedStates, and a resident of Atlanta, in the county of Fulton and State* of Georgia, have invented certain newand useful'lmprovements in Box-Binding Machines; and I do hereby declare the following to bea full, clear, and exact description of myinvention, such as will enable others skilled inthe art to which it appertains to make and use the same, vreference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification. t l

Figs. 23 and 24 are, respectively, a side and front elevationl of the bell and ringing mechanism, showing the upper end ofthe strip clamping plate. Fig.25 is a cross-section on the line 25--25, Fig. 1. Fig. 26, (Sheet 3) is a detail showing a boxcorner,with a strip bent thereover, and affixed. Fig. 27y (Sheet 3) showsconstruction whereby the vwedge is adjusted under the anvil in horizontal section.

In the figures, like referencemarks indicate corresponding parts in all the views.

1 is the base, and 2 the main frame.

3 is a shaft mounted transversely of thel main frame which carries the tly-wheel and clutch mechanism on oneI end, and projects through the frame stopping even with the face of the guide 4, Figs. 1 and 4, andrcarries a wrist-pin 5. The piston 6 slides vertically v10 best shown in Fig. 22, and adapted to grasp the edges of a strip are formed in the sidesv of the groove 9 and extend its'e-ntire length. The lower back corner of extension 8 is rounded as shown in Figs. 1l and 3, and extending along the edge thereof is a shallowA channel 11 as wide as the strip to be affixed to the box cornerin which one'offs'aid strips may lie, and be forced forward. Narrow strips 12 of thin metal are laid upon the remaining portion of the edge so as'to overhang the channel 11 and form a guide preventingl Figs. 20. and 2l show're-. spectively, the front and back ends of the ICO l used.

displacement of the strip, which will be understood on reference to Fig. 8. These strips 12 extend as shown in Figs. 2l and 22 along the under side of the piston 6, overhanging there what is virtually an extension of the channel 11 coextensively with the groove 9, and so forming the aforesaid grooves 10. Thus it is seen that a strip inserted in the upper end of the groove in the extension 8, may be passed around and into the grooves 10 in the piston.

As shown in Fig. 1 atriangular hole is cnt through the piston 6 so as to register with the end of the shaft 3, and into this projects the wrist 5 on said shaft, the pitman 13 being pivoted on said wrist and extending to the lower angle of the triangular hole which is rounded to receive it and there being piv' otally secured to the piston.

The anvil 14 consists of a block of iron seated on a ledge on the side of the frame 2, and carrying on its upper side near its front end flat inclined faces 15 at an angle to each other equal to that of the sides of the groove 9 of the piston. If desired a bar of hard steel 16 may be inserted at the apex for better wearing properties. A plate 17, conforming on its top edge to the angle of the faces 15 of the anvil is secured to the end of the anvil to serve as a guide for holding the box on saidanvil, the bottom of the box being pressed against the face of the said' plate whereby the edges'of the sides of the box which are to be joined and stayed are held parallel along the apex of the anvil. The lower edge of this plate 17 is rounded to facilitate turning the box upon as large a plate as can be The vertical and horizontaldiameter of the plate being the same, and several plates of diiferent sizes and interchangeable being provided it is obvious that a plate of the greatest area of face may be obtained for each size of box and better results be thereby secured.

Vertical adjustment of the anvil 14. to provide for various thicknesses of box-material is provided for in the use of a wedge 18 which is inserted upon the correspondingly inclined ledge of the frame 2 hereinbefore mentioned, and so lies between said ledge and the under side of the anvil, longitndinal movement of said wedge obviously raising and lowering the anvil. This movement of the wedge is conveniently obtained in the construction shown in Fig. 27, in which ligure the back edge of the wedge is shown bent at rightangles and bifurcated. A stud 18a is set in theframe, parallel to the wedge, so that it lies within the said bifurcation, and a thu mbnut18b screwed thereon, which has a neck engaging the bifurcated end of the arm 18. This anvil is held in place by a strap 19 which lies upon same, having its ends fitted over studs 20 set in the frame 2 above and below the said anvil, and held firmly pressed against the said anvil by means of bandwheels 21 screw-threaded onto said studs and bearing on the outer side of the said strap 19. In order to resist the downward thrust of the piston upon the front end of the anvil, a hook-bolt 22 is set in a hole through the frame behind and near the back-end of the anvil, its hook bearing upon the top of the anvil, and a wheel 23 being screw-threaded upon its lower end whereby it is drawn forcibly forward.

As shown in Figs. l, 20, 2l and 22 presserplates 24 are pivoted by their arms 25 on screws 26 in each edge of the piston 6, said plates .projecting below the face of the pis- `ton and a sufficient distance to press the paper firmly against the faces of the anvil before the piston brings the strip to be affixed into contact therewith, and may be if desired slightly rounded so that, as they contact with the box sides and press downwardly, moving outwardly thereon, they will press the box sides firmly against the anvil at the proper relative position to each other and have no tendency to dislocate or abrade the said box sides. In the construction shown in Fig 22 these plates are pressed normally against the sides of the piston by means of a bow-spring 27 operating to diverge the arms 28 projecting upwardly from one end of each plate. A saw-cut or slot 29, Figs. 3, 5 and 6 is made crosswise of the groove 11 on the back edge of the extension 8 of the piston and near said slot with its lower face on a level therewith is a lug 30, which has another lug 31 on its upper end,the use of which will hereinafter be described. A screw 32 is set in the under side of the lower end of the lug 30, and the stationary jaw 33 of the shears is placed upon said screw, being perforated for that purpose, and extends into the slot 29, a set-screw 36 serving to secure its free end and a set-screw 37 bearing against its back edge serving to adjust the blade and hold it in its adjustment, the hole through which the screw 36 passes being slotted to allow a movement when said screw 36 is loosened. The movable blade 38 (also shown in Fig. 13) is also pivotally mounted on the screw 32, an eccentric bushing 41 intervening whereby said shears are adjusted, and enter the recess 29 below the blade 38 as best shown in Fig. 6. The said blade 38 is extended on the side of the screw 32 opposite the cutting end ofsaid blade to form an arm wherein is set a stud 39 which is, in the `construction shown, bifurcated in its lower end, and provided with a pin 40 for a purpose hereinafter more fully set forth.

The bottom of the channel 11 as shown in Fig. 6 and by broken lines in Fig. 5, is rounded as shown at 34 so as to prevent the shears blade from bending the end of the strip, with a short bend near the cut.

Mounted in the lug 31 is a stud 42 which carries thereon, a gear 43,so as to revolve freely and which is provided in the construction shown in Figs. 6 and 7 with a long hub 4:4 which is exteriorly screw-threaded with a IOO IIO

left-hand thread of fine pitch.l A'nut 45 is first screwed en said hub after which the dentated feed-wheel 46 (further shown in Figs. 9 and 10) is screwed thereon, the nut 45 serving to hold the wheel 46 in any set position on the said hub. This construction has particular merit in view of the adjustment of the wheel 46 which is required said wheel 46 to catch same.

being the feed-wheel into the interdental spaces of which the spurs of the metal corner-strips' enter in being fed along the stripway 11 and between the shears to be cut off. Owing to the fact that it is desirable ,to cut the strip between the spurs thereof, the feed'- whelel 46 has circumferential adjustment on the hub 44 and owing to the fineness of the thread thereon the said adjustment may be made without appreciable lateral adjustment of the wheel 46. In said strip-way, back of the wheel 46 as shown in Figs. 9 and 10 is a recess 47, having ledges 48 at its ends whereon rest the ends of a spring-plate 49, so set as to form a depressible bearing for the metal corner-strip as it passes under the feed-wheel 46, whereby in case of the said strip stickingin the channel 11 for any cause, said strip will be depressed by the feed-wheel into the recess 47 against the action of the spring-plate 49 which will allow the feed-wheel 46 to revolve in contact with the points of the spurs on the metal corner-strip without feeding said strip or subjecting the feed-mechanism to unnecessary strain. The mechanism for intermittently revolving the said feed-wheel and stopping same at the right place will lbe now set forth. l

Mounted in the piston 6 concentrically with the curvature of the lower back corner thereof, is the shaft 50 to which is secured the segment 51, as shown in Figs. 1 and 14 which revolves freely on said shaft and has. on it peripheral surface teeth, as shown in the firstnamed figure. A pitman 52 is connected with one of the arms of this segment by means of a wrist-pin 54 set in the end of the wrist-pin 5 on the shaft 3. The said wrist-pin 54 is set in the end of the wrist-pin 5 slightly ahead of the center thereof, so that the segment will be caused to partially revolve with its shaft upwardly a sufficient distance to clear the feed-pawl hereinafter described from the anvil before the piston shall descend sufficiently Just inside the teeth on the segment is va semi-circular series of holes, 55, there being one of said holes near each tooth of the segment except a-few at the top, where they are unnecessary. The second row of holes 56 are screw-threaded, and are situated in the inner edge of the segment. A strap 57 is slotted in one end as shown in Figs. 11 and 12 and a thumb-screw 58 is inserted therein, which is adapted to secure the saidstrap to the segment by being screwed into one ofthe holes 56, said strap carrying a roller 59 on a pin on its other extremity, a leader 60 on the end of said pin entering one of the smaller` holes 55 insuring stability and exactitude of roller 63. The rollers 59 and 63 are merely abutments, and it is not necessary be rollers, although it is preferable.

Reference being had to Figs. 1, 5, 6 and 7 it will be seen that mounted loosely on the end of the stud 42 is a lever 64. On the distal-extremity of said lever is j ournaled a pinion 65, which meshes with the gear 43 on said stud. On the upper end of this lever 64 is an arm 66 adapted *tov engage the roller 63, as shown in Fig. l, and by said engagement to depress that end of the lever 64 slightly, moving it from the position shown in Fi'g.5 toward the position shown in Fig. 1. On the' downwardly projecting end of the lever 64 is a block 67y provided with a face 68, a face 69 inclined thereto, and stop-blocks 70 and 7l. Fastened onthe stud 42 so as to have adjustment pivotally thereon is an arm 72, which is curved so as to bring its end parallel to the said stud. A bell-crank lever 73 is pivoted on the end of said arm and extends so as to contact with.

'the roller 59 on the upward movement of the segment when the said lever is inthe position shown in Fig. 1 said contact throwing'the 1e-V ver into the position shown in Fig. 5, a lug 74 thereon engaging a tooth ofthe gear 43. the upper side of the opposite end of the lever 73 and in a position thereon correlatively opposite the block 67 is a block 75 provided with an inclined face 76, a face 77, and stop surfaces 78 and 79. In the end of the lever 73 is a pin -80 and in the side of the lever 64 is la pin 81, a pulling-spring 82 being connected at each end to the free ends of said pins and acting to draw them toward each other. The reasons for this somewhat complicated construction will be seen on a description hereinafter of the operation of the device.

Secured to the end of the shaft 50 isa disk S4, which has thereon a wrist pin 85, and revolves with the shaft. As shown in Figs. 14 and 15, the said disk and the' hub of the segment 5l on the same shaft are engaged by means of a spring-pressed pin 86, which is set in the said hub, and projects into anoblong recess 87 in the disk, its end being 'pointed and entering conical depressions infeach end of thesaid recess 87, by means of which a slight movement of the disk independently of the hub of the segment is allowed. As shown in Figs. 1, 16, and 17 a guide is formed in the lower end of the segment 5l radially thereof and through this passes the stem 88 of the feed pawl, said pawl being formed of a Strip of steel bent inwardly as shown in Fig. 17 and backwardly as shown in Fig. 16, having on its extremity an upturned lip 89, as shown in both these figures, which lies across the channel 11 in such a position that lit will' when elevated,.enter between two opposite that they OnA IOO

shears, and as the segment descends after the piece of tin is cut from the strip, will carry the piece so cut off downwardly through the groove 11 and so deliver it to the groove in the under end of the piston G. The stem 88 of the` feed pawl is connected by a pitman 90 to the wrist pin S of the disk 84, and it is hence obvious that the movement allowed by the construction shown in Figs. 14 and 15 will cause the feed-pawl to engage and disengage the tin strip. It is necessary to cause this engagement at the same moment the shears work and the segment starts down, and to cause the disengagement just before the time the said segment begins its upward movement. On the opposite en d ofthe shaft 50 and made integrallytherewith in the construction shown in Figs. 3, 18 and 18n is a wheel 91 which is provided with a cam projection 92 having a curved face, while slightly above the cam a stud projects from the side of said wheel 91 and carries a roller 93. A plate 95 shown in the figure just named and also in Fig. 19, is secured to the side of the frame in such a manner that the tappets 96 and 97 will be contacted with by, and act upon the projection 92 and the roller 93 at the proper time in the movement of the piston, the wheel 91 being carried upon and moving with the piston while the plate 95 is stationary on the frame. The pitman` 98 is connected with the wheel 91 by means of a pin 99, its distal extremity being provided with an open-sided slot 100 which is hooked over and engages the pin 40 in the stud 39, Fig. 6. By means of the slot the shears are opened and closed at the extremes of the reciprocating movement of the pitman 98 and in removing from the machine the moving shear-blade 38 a slight twist thereof will detach it from the said pitmau by pass ing the pin 40 out of the open side of the slot.

As shown in Figs. 1, 23, 24, and 25, an upright 101 is secured to the back upper corner of the piston (extension 8) in such a manner as to leave the groove 11 open between the said upright and piston, and a groove 102 is milled in the face, which groove is so formed and situated as to guide the strip along the upright 101 and into the groove 11, a presserplate 103 being hinged to the said bar so as to press upon the strip and keep it in its place in the groove 102. A spring 104 acts to keep the said plate pressed into place. This presser-plate also serves to hold two lengths of strip together after being hooked, as will be understood upon a description hereinafter of the operation of the device. The free edge of the plate 103 may be curved backward if desired as shown in Fig. 25, thereby rendering easier the operation of swinging the said plate slightly back to enable the operator to hook on a new strip the strip slipping freely under the plate in inserting. The upper end of the upright 101 is curved backwardly as shown at 105, and a bell 106 is carried on the upper extremity thereof. Alever 107 is pivoted thereon as shown in Fig. 24 its end being turned back forming an arm 108 to which is secured a clapper 109 the arm and clapper being so formed and extended as to bring the latter close to the bell. A spring 110 acts to draw the lever in 4such a direction as to cause the bell to be struck by the clapper, namely, in the direction shown by the arrow aFig. 24. The object of this bell is to sound an alarm as soon as the upper end of the strip enters between the upright 101 and the presser plate 103. The construction necessary to complete this function is as follows: An arm 112 is formed on the lever 107 and has a backwardly extending lip 113 turned thereon. l/Vhen the strip is in the position shown by broken lines in Fig. 24 this lip 113 rests against its edge the engagement of the spurs on the strip with the groove 102 preventing a displacement of thestrip thereby. As soon as the strip is drawn downwardly by the feed-wheel until the upper end` of the strip is below the said lip 113 the tractile spring 110 having its fixed end fastened to the upright 101 above the pivotal point of the lever 107 will cause a movement of the lever to sound the alarm. In order that there shall be no strain edgewise on the strip which could possibly cause a displacement thereof under any conditions and to hold the lip 113 out of constant engagement therewith, an upward projection 114 may be provided if desired on the lever 107 opposite the lip 113, and bear upon the opposite edge of the tin-strip.

A finger 111 on the upper corner of the part 105 of the upright 101 serves as a bearing point for the strip opposite the arm 114 and acts also to prevent the strip becoming disengaged from the said arm upon the sudden downward movement of the piston in operating. The strip now has two opposite bearing points above the lip 113 and the lever 107 is by the bearing of the arm 114 on the edge of the strip, held in such a position that the lip does not touch the strip until same is drawn below said arm 114 when the lever moves slightly and brings the lip against the said strip from which position it trips the lever 107 as soon as the strip descends a sufcient distance.

The piston in its movement as before stated stops at4 midst'roke in its movement downward and hence starts at the same point the shaft making a single complete revolution. To produce this intermittent motion a peculiar clutch mechanism is required that is,

`a clutch which when caused to engage the `continually revolving element will make one complete revolution, and stop automatically, ready to again be thrown into action.

The operation of this device is as follows: The device is in its normal position as shown in Fig. 1. A strip of tin bearing spurs suit able for aftlxing is placed between the projection 114 and the lip 113 of the bell-lever 107, and pressed under the free edge of the spring-pressed plate 103 until the spurs register with the groove 102, when the plate IOO ITO

closes, pressing said spurs into thegroove. The strip is then manually drawn downwardly until its lower end enters the groove 1l and passes downwardly through same to the feed-wheel 46, after which one revolution of the main shaft of the' machine, will, as hereinafter specilied cause the said feedwheel to force the strip down to and slightly through the shears, and cause said shears to cutoff the projecting piece which is the only waste occurring at any time during the operation of the machine, unless from accident it shall be necessaryto insert another strip to forni the initial one of a connercted series. The strips are fed continuously to the machine by allowing the strip to be fed down-- ward as it is used until the bell rings, which' occurs as hereinbeforementioned as soon as the upper4 end of the strip has passed the projection 113 and hence is between the bar 101 and the hinged plate 103. The operator then takes a new strip and places same on the bell-lever as just described above, and enters saine in the above-described manner between the upright and hinged plate draW- engage,and their operation both in feeding and being affixed to the box-corner is precisely the same as a continuons strip the length of both. Strips may thus be successively in serted and connected and their entire length isutilized, leaving no Waste of metal which is an item of considerableimportance. The machine is now in its normal position and is charged with a strip `ready toV be fed downward. The anvil 1.4 is moved on its seat until it projects under the piston from its back side just the depth of the boX to which the strip is to be affixed, and, by means of the wedge 18 the said anvil is raised or lowered to accommodate the thickness of the board used in the box. The number of spurs which a strip should have which would be of a length sufficient for the depth of the box is then determined, and the strap 57 is so set that the leader 60 will enter a hole in the series 55, which is a proper number in the series. These adjustments being made, the machine is then started by throwing in a suitable clutch, whereby connection is made between the fly-wheel which has been previously set revolving and the shaft 3, starting said shaft to revolve in the direction of the arrow b thereon in Fig. 1.

This movement of the shaft starts the piston descending, and through the pitman starts the segment upward on its partially rotary movement. The cam 91 is in a position normally which is shown in Fig. 18a and on thev of this piston, and the revolution of the seg ment and cam 91 brings the projection 92 into contact with the tappet 96, which causes a movement of the shaft 50 to the limit of the slot 87, Fig. 15, independently of the `movement of the segment, and in the directionof the arrow d, Fig. 1, which causes the feed-pawl 89 to move downwardly as in disengaging from between the spurs of a strip, were one at this point of the operation in the die on the under end of the piston. As the segment 51 ascends, itactuates thegear 65, said gear having been previously thrown into engagement therewith, which will be hereinafter described, and through it drives the feed-Wheel 46, by means of the gear 43, said feed-wheel revolving in the direction of the arrow eFig. 1, and drivesthe strip downward through the groove 11 and the shears, and continues so to` do until the roller 59 on the strap 57'comes into .contact with the end of the arm 73, which partially revolves said lever in the direction of the arrow f Fig. l, releasing the engagement between the blocks 67 and 75 and inserting the block 74 between two teeth of the gear 43 whereby the revolution of the gear 43 and the feed-wheel is instantly stopped allowing the spring 82 to swing the lever 64 on the stud 42 which swings the axis of the gear 65 in a direction fromthesegment and causes the said gear 65 to travel upon the teethof the gear 43 and so 'be revolved inthe saine direction as previously shown and thus be drawn out of mesh with the teeth of the segment, rolling as it is drawn out. In this manner the piece of tin has been fed down so as to project below'the shears a sufficient distance to tit the box-corner, and it now remains for the mechanism to cut same off and feed it into the grooves on the lower end of the piston 6.- The piston y6 then reaches its limit of depression applying the pressure, and commencing its ascent, the upward movement ofthe segment 51 continuing, and hence the revoluioo tion of the cam-Wheel, continuing in the diready to close, the feed-pawl being directly under the shears and ready to engage between the spurs of the strip as before stated, said strip .being in position to be cut and engaged.

The wrist-pin 5 is, at this time, approaching t and passing the dead-center relative to and .distal fromthe pin 53 of the segment, and

hence the segment is, practically at a standstill, andl the shaft 50 is moving upward in the direction of the arrow c in Fig. 18.

Owing to this motion the roller 93 is brought into forcible and operative contact withthe tappet 97 which partially revolves the `cam` wheel 91 in the direction of the arrow c Fig. 18 imparting thereto a very quick motion to the limit of` the slot 87 which partially revolves the disk in the direction opposite the arrow d Fig. 1 thereby quickly pulling the lip 89 on the feed-pawl 88 between the pair of spurs of the strip next below the shears, thereby engaging same, and simultaneously closing the shears, thereby severing the strip. The segment 51 now starts downward carrying the section of the strips so cutoff downwardly through the groove l1 carrying it to the grooves in the lower end of the piston 6 and into a position to be affixed. During the time the segment continues downwardly carrying the strip the shears stand closed on account of the lost motion due to the slot 100 in the pitman 98, but during .the latter part of such movement the shears are partially opened by the end of the slot 100 coming into contact with the pin 40 of the shears, and the opening is completed by the action of the cam wheel and tappet which disengages the feed-pawl in which open position it remains until again closed, as hereinbefore specified. Just before the segment reaches its downward movement the roller 63, Fig. 1 is brought into contactwith the arm 66, Figs. l and 5, the lever 72, and contiguous parts being in the position shown in Fig. 5 at this time, as they were left by the operation previously described, the feed-wheel 46 being at rest, and engaging spurs of the strip to be fed. This engagement of the roller 63 and arm 66 moves the lever 64 on the pivot 42 in the direction of the arrow??l Fig. 5 a sufficient distance to bring into operation the two inclined faces 69 and 76 of the blocks 67 and 75 respectively, and at that time the spring 82 acting through the arm 8O moves the lever 73 in a direction opposite the arrow f Fig. l, which causes the said inclined faces to move upon each other and continue the movement of the lever 72 just mentioned until the gear 65 shall be meshed with the teeth of the segment. During this time the block 74 has been engaged with the teeth of the gear 43 holding same from revolving, whereby a planetary movement has been imparted to the gear 65 causing it to roll into engagement with the teeth `of the segment. As soon as this engagement is completed the block 74 has been Withdrawn from the teeth of the gear 43 and hence same is ready to be revolved and perform the operation of feeding the strip and being released from engagement with the segment, both of which have been described. The stops and `7l and the stop surfaces 7 8 and 79, co-operate to limit the movement of the lever 7.2 in obedience to the action of the spring 82; and may obviously be so constructed and placed as to subserve this purpose in any desired way. The parts are new in position to repeat the operation from the beginning.

The operation of aflixing the strip as far as it relates to the operation of those parts not l hereinbefore described is as follows: The strip of tin has been by the mechanism inserted in the piston as hereinbefore set up. Theoperator then places the box in position the bottom resting on the plate 17 and held thereon by his thumbs, pressing the fore-finger of each hand upon the sides to be joined and bringing the same against the faces 15 of the anvil, causing the edges thereof that are to be joined to lie approximately parallel along the apex of the anvil. The piston descending first sets the sides in position by bringing the rounded edges of the presser-plates 24 into contact therewith and then affixes the strip in the usual manner by pressure.
